In their pioneering work carried out at Berkeley in the mid-1980s, the laureates, John Clarke John Martinis and Michel Devoret, first demonstrated that a collective electrical variable, namely the phase difference across a Josephson junction, obeys the rules of quantum mechanics, an issue raised by A.J Leggett. They measured the so-called macroscopic quantum tunneling rate of the junction out of its zero-voltage state, and they demonstrated that the phase has well defined quantum states between which transitions can be induced by applying a resonant microwave signal. These results triggered a huge activity in the field of superconducting quantum circuits for first making quantum bits, and later quantum processors and quantum sensors. I will review some of the main results obtained in this area, and noticeably those of our Quantronics group at CEA Saclay.<\/p>\n<\/div><\/section><\/p><\/div><\/p>\n<div  class='flex_column av-twd2m0-9f72c499cbb89f30341f461adfbf267e av_one_fifth  avia-builder-el-6  el_after_av_three_fifth  avia-builder-el-last  flex_column_div av-hide-on-mobile'     ><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":69380,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3,8],"tags":[],"class_list":["post-76728","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-a-la-une","category-actualites"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/76728","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=76728"}],"version-history":[{"count":16,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/76728\/revisions"}],"predecessor-version":[{"id":77017,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/76728\/revisions\/77017"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/69380"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=76728"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=76728"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=76728"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
